Filed:

Nov 21, 2000

Appl. No.:

09/717724

Inventors:

Donald C. Borio - Knoxville TN
David J. Muraskin - Knoxville TN
Phillip C. Rader - Knoxville TN
Mark A. Walters - Knoxville TN

Assignee:

Alstom (Schweiz) AG - Baden

International Classification:

B01D 5350

US Classification:

42324301, 423237, 42324303, 42324306

Abstract:

A flue gas mixture containing sulfur oxides is scrubbed in a countercurrent spray tower absorber with a spray of ammonium sulfate liquor and the scrubbed gas stream containing ammonia aerosols, sulfur trioxide aerosols and ammonia slip is passed to a wet electrostatic precipitator for the removal of the aerosols and slip. The ammonium sulfate liquor in the absorber system is passed into a separate reaction tank where ammonia and air are injected. The ammonia and sulfur oxides react in the separate reaction tank to form ammonium sulfite which is oxidized to the sulfate by the air. The gases and vapors from the separate reaction tank are separately scrubbed and the gases then returned to the absorber.

International Classification:

F23G 504

US Classification:

110347

Abstract:

An integrated method of removing alkali metal compounds from sulfur-bearing coal is disclosed. The coal is comminuted (4) and mixed (10) with water (8) to form a slurry (12). In the preferred embodiment, the slurry (12) is comingled with an SO. sub. 2 -bearing gas (16) in a transport pipeline (52) to form an acidic slurry which dissolves the alkali compounds out of the coal. The slurry is then separated (22) into a solid portion (24) and a liquid portion (26), the solid portion (24) being combusted (34) to form the SO. sub. 2 -bearing gas (16).

International Classification:

B01D 53/62
F01N 3/20
B01D 53/56

US Classification:

423220, 422169

Abstract:

A method and a system are provided for processing a gas stream wherein the gas stream is passed through an absorption process thereby forming and CO2-lean gas stream having ammonia therein and a CO2-rich stream. The CO2-lean gas stream having ammonia therein subsequently is passed to a selective catalytic reduction process.
